Cristiano Ronaldo hailed an "unbelievable" week for Real Madrid but said he was "sad" for Manchester United after his goal knocked them out of the Champions League.

"We still have a long way to go in the competition," Ronaldo said. "We have beaten one of the best teams in the world in Manchester United. We will go step by step, but we are in good shape. This [last] week, it was unbelievable to win two games against Barcelona and one against Manchester United. It was fantastic for us, we are in good shape, we are confident and we want to go like that.

"It was an unbelievable night, a very emotional night and what the supporters did for me was massive," he said of his reception at Old Trafford. "I am never going to forget that moment. For one side I feel happy, for Madrid to go through to the next round, but for the other side I feel a little bit sad because it is not easy to forget this home. I played for six years here and the people were very nice to me. I came here like a child. It was quite a strange feeling.

"Not just for this game, but the first game too. I felt a little but shy in my game and I have feelings which I can't explain. I am happy because Madrid got through, I defend my colleagues and I play for Madrid so I try to do my best all of the time."
